[Buildroot] Putting qtwebkit on a diet

[Stefan Fröberg]

Update: I just tried it and the results are these:

Stock, uclibc qt5webkit size on target:
32MB

Modified uclibc qt5webkit build with "minimal" and
"use_cross_platform_context_menus" (needed for successfull build)
settings, size on target:
22 MB

So it would save about 10 MB
